BED LOCK.

Application filed March 29, 1922.

To all whom it may concern:

Be it known that I, Porn Gone, a citizen of the United States, residing at Browns ville, in the county of Haywood and State of Tennessee, have invented a new and useful Bed Lock, of which the following is a specification.

This invention aims to provide novel pmeans for holdinga bed rail on a bed post in such a way that the bed rail may be reversed. Another object of the invention is to provide novel means for securely binding the rail in the socket of the bed post.

In the drawings F ip-Euro 1 shows in plan, a device constructed in accordance with the invention, parts being broken away; Figure 2 is a side elevation; Figure 3 is a fragmental longitudinal section taken through the socket; Figure 41- is a fragmental top plan showing a portion of the socket and attendant parts.

The numeral 1 marks a bed post carrying a box-like socket 2. Although the bed post 1 has been shown as being of circular cross section, the socket 2 may be mounted on any kind of a bed post. The socket 2 has an opening 1 in its top and an opening 5 in its bottom, the openings being located symmetrically with respect to the axis of the socket. The opening 41 preferably is some what larger in diameter than the opening 5.

The numeral 6 designates, generally a bed rail. the body of the bed rail comprising a first flange 7 and a second flange 8 disposed at right anglesto the first flange 7. A block 9 is fitted in the angle defined by the flanges 7 and 8. The block 9 is cut away to form a first flange 12 cooperating with the first flange 7 of the body of the bed rail, and to form a second flange l1 cooperating with the second flange 8 oi? the body of the bed rail. A securing element 15 connects the flanges '7 and 12. and a securing element 14 the flanges 11 and 8, the block 9 thus being held on the body of the bed rail. The block 9 has a reduced extension 16, extended into the socket 2 and completely filling the socket transversely. The flanges 7 and 8 of the rail, and the block 9 abut against the inner end of the socket 2, as shown at 17. A. reduced tongue 18 projects from the Specification of Letters Patent.

} the tongue will be Patented June 20, 1922. Serial No. 547,765.

part 16 of the block 9. The inner surface of the tongue 18 is supplied with a transverse groove 19 adapted to cooperate with the openings 4- and 5 in the socket 2. The inner surface of the tongue 18 coincides with the axis of the socket 2, that is, in cross section, the tongue 18 is approximately one half the size of the socket 2. The groove 19 is so formed in the inner surface of the tongue 18 that when a tapered pin 20 is mounted in the openings 1 and 5 of the socket and in the groove 19 of the tongue, moved diagonally of the socket as indicated by the arrow A. The 'esult is that the end'of the bed rail and the end of the block 9, are crowded against the inner end of the socket 2, and, at the same time. the tongue 18 is crowded transversely against one side of the socket, an unusually tight joint resulting. Since the cross sectional area of the tongue 18 is one half the cross sectional area of the socket, the bed rail 6 may be reversed on its axis, that is. the tongue 18 may be disposed adjacent to the opposite side of the socket 2 from that shownin Figure 1.

hat is claimed is:

In a device of the class described, a bed post having a socket comprising walls; a rail provided with a shoulder, and having a tongue received in the socket, the cross sectional area of the tongue being approximatoly one-half the cross sectional area of the socket, the tongue having a groove in its inner surface, and the socket having an opening; and a retaining pin inserted into the opening and into the groove, the opening and the groove being so located with respect to each other that, when the pin is inserted intov the opening and into the groove, the pin will clamp the shoulder against the end of the socket and clamp the tongue against one wall of the socket.

In testimony that I claim the foregoing as my own, I havehereto afliXed my signature in the presence of two witnesses.
